I don't recall George mentioning anything about Dunk and Egg in particular. He of course was asked his publishing schedule for ADwD. George said he has been traveling so much he hasn't really had time to write much. But he only has one appearance between now and World Con which is a Columbus con over Memoroial day. So he expects to start making progress soon.
As others have said the reading was the first Tyrion Chapter.
The Westeros network consists of several different sites, including a forum and a wiki, for all your A Song of Ice and Fire needs.
